Generally, all applicants must be U.S. citizens or eligible immigrants to apply for a TWIC. In addition, an individual must not be found to have terrorist ties, may not have prior convictions for certain crimes, and must have sufficient mental capacity to be approved for a TWIC.
Immigrant Status – An individual must be a U.S. citizen or eligible alien in order to receive a TWIC. TSA provides a list of acceptable documents that are sufficient to verify a lawful immigration status, which the applicant should take to the enrollment center.
Terrorist Ties – All applicants are screened against government terrorist watch lists. If TSA determines that an applicant has a connection to terrorist activity, it can deny the applicant a TWIC.
Mental Competency – An applicant may be denied a TWIC if TSA determines that the applicant lacks the mental capacity to hold a TWIC.
Criminal Disqualifiers – The TWIC Final Rule provides a list of permanent and interim disqualifying offenses.
